FlRE-ANNLHILATOR.

SPECIFICATION forming partof Letters Patent No. 257,593, dated May 9,1882.

Application filed November 25, 1881.

To all whom it may concern:

Be it known that I, IsIDoR KITSEE, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented anew and useful Improvemeut in Fire-Annihilators, of whichthe following is a specification.

My invention relates to improvements in that class of fire-annihilatorswherein chemical agents areheld in reserveiu magazines and aredischarged automatically into a common receptacle, wherein they uniteand form a fireextinguishing gas or vapor. Experience has demonstratedthat when such fire-extinguishin g gases and vapors are kept preparedfor use for anylength of time in a completed condition they becomeliable to deteriorate and lose their essential qualities, and that bykeeping the when required for use the best results are attained.

I do not herein claim broadly the retention of gas and vapor producingchemicals in separate friable places of deposit and their ejection intoa common receptacle.

My present application relates to certain operative devices, as hereindescribed, for carrying into practice the production of the gases andvapors, in the manner and for the purpose as hereinbet'ore set forth.

The drawing represents two friable vessels, above which is suspended aweighted bar and an under receiving-generator. The operation of thedevice, as indicated by arrows on the drawing, is represented in dottedlines.

A A are vessels, made of glass or an y suitable friable material, havingcovers a. a resting on brackets or bases B B; Each of these vesselscontains a given quantity of required chemicals, and any number of suchvessels may be used.

O is a receivingreservoir or generator, which (No model.)

may contain water, 0, or aiiy chemical agent. It is preferably closedwith trapcovers c c.

D is a bar having weighted ends, dd, suspended by a fusible wire, E, ora wire having fusible joints 0 e; or the wire may be anchored in afusible plug, 0'. The bar D has vertical rods d d extending downward.

When my device is placed in a building in which there is anincipientfire and the temperature rises to adegree sufficient to fuse the wire Eor the connections 6 e, the bar D falls by gravity and its weighted endsat (1 break the vesselsAA and release their contents. At the same timethe rods d d open the traps c c of the generator 0, and all thechemicals within the vessels A A are at once emptied into the generator0, where they unite with any material contained in the generator O,andthereby produce the required gas or vapor, which escapes through theopened top of the generator.

Having now fully described my invention, what I claim is 1. In anautomatic fire-extinguisher, friable vessels supplied with chemicalswhich, when commingled, form a fire-extinguishing gas or vapor, and agenerating-reservoir to receive the contents of said friable vessels, incombination with weights held suspended by fusible connections,substantially as described.

2. In an automatic fire-extinguisher, the friable vessels A A,the'receivinggenerator 0, having traps c c,in combination with dependingrods cl d, and the bar D, having weighted ends-d d, held suspended bymeans of fusible connections, the melting of which is adapted to causethe weighted-arm to fall, thereby breaking the friable vessels A A andemptying their contents into the generatingreservoir, substantially asdescribed.
